4150 Pro-Power Plate Only (100-500HP)

The 4150 Pro-Power Plate Only (100-500HP) by Nitrous Express is a precision fuel distribution component designed for high-performance nitrous oxide systems. Built for serious engine builders and tuners, this plate serves as the critical interface between your nitrous supply system and your intake manifold, ensuring optimal fuel atomization and consistent power delivery across a wide 100 to 500 horsepower range.

Whether you're building a street-strip hybrid or a dedicated drag engine, this Pro-Power plate is engineered to handle the demands of controlled nitrous injection without compromise. Nitrous Express engineered the 4150 Pro-Power plate to work seamlessly with 4150-style carburetors and EFI throttle bodies, featuring precision-machined fuel distribution galleries that promote even fuel atomization when nitrous is introduced.

This plate is ideal for builders who want modular control over their nitrous system—tuners appreciate the ability to swap jets, adjust fuel mixture, and customize their fuel delivery path without replacing the entire setup. Weighing approximately 1.05 lbs with compact dimensions (10.5 x 2.3 x 10.75 inches), the Pro-Power plate minimizes parasitic weight and heat soak while maintaining the structural integrity required for consistent system performance under high boost and high nitrous flow conditions.
